Abstract
Philostratos records that the ephebes of Athens wore a black χλαμς to commemorate their murder of Kopreus in defence of the Herakleidai. Both the Herakleidai and a herald of Eurystheus appear in Herakleidai of Euripides, but the murder of the herald is not at issue, nor indeed is there any reference to ephebes or ephebic practice. This state of affairs will cause no surprise, for tragedy regularly selects its story-line from the wider range of the myth, and later uses to which that myth may be put have no necessary bearing on the play. It is however the contention of this article that the religious and social context of Herakleidai has been neglected, and that careful reconstruction of that context from later sources, restoring to us the associations that Euripides could assume in his own day, is an essential prerequisite to any aesthetic or dramatic interpretation of the play
